Early EVs we’re relatively slow in acceleration. Higher end new EVs have performance car acceleration rates.eventually EVs will become more mainstream. From a complete stop, what 0-60 and 1/4 mile time would you consider to be just enough for a basic commuter EV (think Corolla type vehicle)? Would a reduction in maximum acceleration rates result in longer distance per charge? Would software controls; like Eco, Normal, & Sport; be easier than on an ICE vehicle? For a higher end, more traditional luxury, vehicle could they do software engineering to give the feel of the old school high torque acceleration of old luxury V8 sedans?

To me, for a basic commuter vehicle an acceleration rate of 0-60 of 8 to 10 seconds and a 1/4 mile of around 17 seconds should be fine for those who aren’t into driving enjoyment. That would be the normal mode settings. Eco would slightly reduce this for extending range and sport would reduce these times while reducing the range. I like low end torque feel but I like the linear acceleration of the torque gently pressing me into the seat. It’s hard to express exactly how this feels. Instant torque and power can shove you hard into the seat. That’s fine for performance vehicles. My wife can’t handle such acceleration rates. Her spinal problems causes her pain in the spine with such acceleration rates. A gentle press into the seat is easier for her.

Todays EVs are crazy fast. The new F150 Lightning can do 0-60 in a little of 4 secs. This is a huge tail pickup truck. There is a Tesla that does 0-60 in 1.9 secs. EVs have a crazy advantage of ICE.

IMHO, that acceleration is really nothing more than a party trick. How often does someone need a 2 second 0-60?

I've got two EVs and two turbodiesels that are very different from each other:

2001 VW Golf TDI (moderately modified) - 46mpg manual transmission with a Torsen differential, 640-700 mile range per tank, Slow off the line with a 0-60 in 9.5 seconds, but very good passing power on the highway. 4cyl good for about 120hp and 255lb-ft torque.

2006 Chevy 2500HD Duramax (stock) - 16mpg, 6-speed transmission, 260-290 mile range, 0-60 in about 9 seconds, 8cyl good for 320hp and 650lb-ft.

2013 Fiat 500e - 24kWh battery pack (20kWh usable), reduction gear transmission mated to an 83kW electric motor, 0-60 in about 9 seconds but incredibly poor passing power at speed above 70mph. The reduction gear creates a bias for wheel power at lower speeds compared to higher speeds. Range is good for 50mi at freeway speeds, 85mi around the city.

2013 Tesla Model S 85 - 81kWh battery pack (77kWh usable), reduction gear transmission mated to a 278kW electric motor, 0-60 in under 6 seconds and incredible passing power. Range is between 200-230mi.

The Tesla has a much smoother and premium feel from the powertrain. The Fiat is just fine, but it pretty much an off the shelf powertrain that utilizes a Samsung battery pack and a Bosch SMG 180/120 motor that is pretty much the same front power propulsion used fo the Porsche 918.

Just watched a Motorweek test of the Nissan Leaf Plus with a 0-60 of 7.1 seconds. Of all the EV cars I’ve seen, the Leaf is closest to my size, performance, & price. Sadly I would need a licensed electrician to install a charging port at the house before I could consider an EV. Another issue is the wife. Wife has health issues and ease of getting in and out is a factor for my next purchase. Another issue is there are no EVs at any local dealerships at this time. I would have to travel 2 hours or more to see a new model in person for a test drive. The local Hyundai and Kia dealerships do have an EV but they’re at a slightly higher price range than we can afford right now.

We would have the same issue, although, I just saw an ad for a transfer type switch that plugs into the 240 outlet that one would use for there dryer or washer.

Would still need an electrician to run the line to the carport and add a breaker for the new line. Would want ground fault protection. This is south Louisiana.
